Plaster is a beautiful, long-lasting wall covering, but it is vulnerable to moisture intrusion, which can damage or even destroy the surface. Learning to recognize the signs of water behind the plaster is especially crucial if you own a historical home, allowing you to get repairs before the damage is too severe. Below are some of the most common signs that you may be dealing with water-damaged plaster.

How to Tell If Your Plaster Has Water Damage

1. Musty Odors

Water behind the plaster creates an ideal growing environment for mold, which can cause respiratory issues and other health problems. Mold and bacteria inside the house can often leave a persistent, musty odor that doesn’t subside no matter how much you clean.

2. Dark Patches

Moisture intrusion often leaves dark spots and stains on plaster walls and ceilings, which you cannot clean away. Peeling paint and flaking plaster often accompany these spots, which can eventually destroy the entire wall if you don’t fix the source of the problem.

3. Peeling Paint & Wallpaper

Excessive moisture in the walls make adhesives less effective and loosens the bonds holding the paint to the surface. Peeling paint or wallpaper often means moisture has suffused the plaster, especially around seams and cracks.

4. Pest Infestations

Cockroaches, termites, ants, and other pests need water to survive, so a sudden increase in pest populations can indicate moisture intrusion. Of course, a variety of factors contribute to pest infestations, so a thorough examination and a professional inspection may be necessary to discover the source.

5. Efflorescence -  fflorescence means to flower out in French. It is a result of moisture dissolving salt inside the plaster. It usually shows up as bubbling and or  a chalky, white substance. This is a clear indication of moisture intrusion. Remember this efflorescence must be removed before honest craftsmanship can take place.
